Modern LG refrigerators are equipped with many functions designed to make life easier user and extend the shelf life of products. One of the most useful, but often questionable options is mode Freeze Temp. Many equipment owners notice this indicator on the control panel, but do not always understand its real purpose and mechanics of operation. In this material we will analyze in detail how this system works and why your family needs it.
In two-chamber models with a system No Frost or Total No Frost temperature conditions are often interrelated. The function Freeze Temp allows you to force and temporarily increase the cooling of the freezer. This is critical when loading large quantities of fresh food that needs to be frozen quickly to preserve its structure and vitamins. Without this mode, the freezing process would take too long, which could negatively affect the quality of meat, fish or berries.
Understanding the principles of operation compressor and evaporator helps to operate the equipment correctly. Activating this function signals the electronic control module to start the engine at maximum speed. This allows you to reach extremely low temperatures in the shortest possible time. Below we will look at the technical nuances, operating modes and typical use scenarios.
Principle of operation and purpose of the function
Mode Freeze Temp, which can also be referred to as "Super Freeze" or "Super Freeze" depending on the series of the refrigerator, it works on the principle of priority cooling. When activated, the system ignores standard compressor shutdown cycles. Inverter motor goes into continuous operation mode, directing the entire refrigerant resource exclusively to the freezer compartment.
Usually the standard temperature in the freezer is about -18°C. When the function is turned on Freeze Temp the indicator can drop to -24°C or even lower, depending on the model. This creates what is called "shock" cooling. Large ice crystals do not have time to form inside the cells of the products, which destroy the fibers. As a result, after defrosting, the meat retains its juiciness and the vegetables retain their shape.
It is important to note that this function is not endless. The electronics LG refrigerator are programmed to automatically turn off the mode after a certain period of time, usually from 18 to 72 hours. This is done to protect the equipment from overheating and prevent excessive power consumption. If you need to extend the mode, the button will have to be pressed again.
⚠️ Attention: Prolonged operation of the compressor in forced freezing mode increases the load on the mechanical components. Do not use the function unless really necessary, for example, for freezing already chilled semi-finished products.
It is also worth mentioning the distribution of air flows. In systems with a single compressor, increased freezer operation can briefly increase the temperature in the refrigerator compartment. However, modern algorithms Smart Cooling minimize this effect, quickly returning the indicators to normal after the cycle is completed.
How to activate and configure the mode
Function control Freeze Temp in LG refrigerators is simplified as much as possible and is carried out through the touch panel or mechanical buttons located on the front side of the door. In some premium models, configuration is possible through an application on a smartphone, which allows you to remotely control the freezing process. To turn on the mode, you need to find a button with the corresponding name or a snowflake icon. Pressing will activate the indicator. Depending on the version, you may need to hold the button for 3 seconds to unlock the control panel. After activation, you will hear a characteristic sound signal confirming the change in operating parameters. LG ThinQ on a smartphone, which allows you to remotely control the freezing process.

- ⏱️ Check the operating time: by default, the system works for about 24-48 hours.
- 🔄 To manually turn off, press the same button again until the indicator goes off.
If you use a smart home, a notification about the completion of the cycle may come directly to your phone. This is convenient, as it allows you to turn off the mode in time if the food is frozen ahead of time, and save energy. In models with a display, the current temperature will be displayed in real time.

Freezing modes and their differences
In different lines of LG refrigerators, the functionality may be called differently, but the essence remains similar. Understanding the differences between the modes will help avoid confusion. The main difference lies in the speed of reaching the target temperature and the duration of operation at the maximum capacity.
There are several variations in the execution of this function. In basic models, this is a simple increase in compressor operation. In advanced versions with DoorCooling+ or Multi Air Flow the algorithm of operation of the dampers and fans also changes. Cold air is directed more intensively and evenly throughout the entire volume of the chamber.
Comparative table of operating modes:
| Parameter | Normal mode | Freeze Temp | Eco mode |
|---|---|---|---|
| Temperature | -18°C | up to -24°C and below | -16...-17°C |
| Compressor operation | Cyclic | Continuous | Reduced power |
| Energy consumption | Standard | Maximum | Minimum |
| Purpose | Storage | Quick freezing | Energy saving |
The choice of the right mode depends on your purpose. If you are simply storing inventory, the standard settings are sufficient. The mode Freeze Temp was created specifically for the moment of loading. Using the "eco" mode to quickly freeze fresh fish will lead to spoilage of the product, since the temperature will drop too slowly.
Impact on food safety
The main purpose of using the function Freeze Temp is to preserve the quality of the products. Rapid passage through the "crystallization zone" (temperature range from 0°C to -5°C) prevents the growth of large ice needles inside the cells. This is especially true for products with a high moisture content: berries, mushrooms, meat and fish.
During slow freezing, the water inside the cells manages to collect into large crystals that tear the cell walls. After defrosting, such a product loses juice, becomes flabby and loses its taste. The function Super Freeze eliminates this process, providing "shock" freezing.
It is especially useful to use this mode for:
- 🥩 Fresh meat and poultry - preserves the texture of the fibers.
- 🐟 Fish and seafood - prevents the appearance of unpleasant odor during defrosting.
- 🍓 Berries and fruits - retains the shape and integrity of the skin.
- 🥟 Homemade semi-finished products - dumplings and dumplings do not stick together.
⚠️ Attention: Do not fill the freezer with room-sized products temperature to failure. This can lead to a temporary increase in temperature in adjacent compartments and thawing of already frozen reserves.
In addition, quick freezing helps preserve more vitamins and microelements. Prolonged exposure to moderate cold triggers enzymatic processes that spoil the product. Rapid cooling “preserves” beneficial properties.
Typical user mistakes
Despite the simplicity of control, users often make mistakes that reduce operating efficiency LG refrigerator. One of the most common is leaving the mode Freeze Temp on on a permanent basis. This not only consumes excess electricity, but also leads to over-drying of food and excessive load on the compressor.
Another mistake is loading warm dishes. If you put hot soup in the freezer, even the super-freeze mode will not instantly save the situation. The heat load will be too great, which can cause freezing of the evaporator and a decrease in cooling efficiency in other zones.
Frequent errors during operation:
- 🚫 They forget to turn off the mode after the cycle is completed (it works in vain).
- 🚫 They block the air ducts with products, blocking access to cold air.
- 🚫 They open the door too often during the function, releasing warm air.
- 🚫 They try to freeze food in unsealed containers, which leads to freezing of moisture.
It is also worth remembering about hygiene. Regular defrosting and washing of the refrigerator is necessary even for models No Frost. Ice deposits on the sensors can distort the temperature readings, and the system will not work correctly, believing that the desired temperature has not yet been reached.
What to do if the products are frozen to the shelf?
If the products are frozen, do not tear them off by force under any circumstances - you can damage the coating or the product itself. Turn off the super freeze mode, wait 5-10 minutes or pour warm (not hot!) water over the bottom of the container. The ice will quickly melt, and you will be able to remove the contents without damage.
Diagnostics of problems and error codes
LG refrigerators are equipped with an advanced self-diagnosis system. If the function Freeze Temp does not turn on or the temperature does not drop, error codes may appear on the display. Most often, problems are associated with a malfunction of the temperature sensors or fan.
For example, the code rF indicates a defrosting error, which can indirectly affect the ability to freeze. The code Er FF indicates a malfunction of the freezer fan. If the fan does not spin, the cold is not distributed, and the sensor does not detect a decrease in temperature, which is why the mode may not activate correctly.
Main temperature-related codes:
- ❄️ Er FS —freezer temperature sensor error.
- 🌬️ Er FF —freezer fan error.
- 🔌 dH —defrost error (often requires defrosting the refrigerator for 24 hours).
In most cases, a full reboot cycle helps to eliminate false errors. It is necessary to unplug the refrigerator for 10-15 minutes. This will clear errors in the electronic module memory. If after turning on the problem repeats, you need to call a technician.
Energy consumption and savings
Using the mode Freeze Temp inevitably leads to an increase in energy consumption. The compressor operates at the limit of its capabilities, consuming maximum current. However, given the short duration of use (usually no more than a day), the financial impact on the family budget remains minimal.
Modern inverter compressors linear type installed in LG are able to regulate power more smoothly than older models. However, in Super Freeze mode they consume significantly more. If you have a limit on electricity or use autonomous power supply, this is worth considering.
To minimize costs, it is recommended:
- Activate the mode only when the chamber is fully loaded with fresh products.
- Monitor the operating time and turn it off function immediately after deep freezing.
- Do not open the door unless necessary, so as not to lose cold.
In the long term, proper operation of the function prolongs the life of the refrigerator itself. Rare but intense operating cycles are better for the engine than constant wear and tear in borderline modes. The main thing is not to abuse the function unnecessarily.
Is it possible to keep the Freeze Temp mode on all the time?
Technically, the refrigerator will work, but this is not recommended. Constant operation at maximum speed will lead to accelerated wear of the compressor, over-drying of food and a significant increase in electricity bills. For normal storage, the standard mode is sufficient.
Why did the temperature in the refrigerator compartment rise after turning on Freeze Temp?
In models with one compressor, the system prioritizes cooling of the freezer in this mode. This is a temporary phenomenon. As soon as the freezer reaches the target temperature or the mode is turned off, the temperature in the refrigerator compartment returns to normal.
How long should you keep food in super-freezing mode?
Usually 3-5 hours are enough for a small volume or 12-24 hours for a full load of the chamber. After the products have completely frozen (become solid throughout the entire volume), the mode can and should be turned off.
Does the mode affect the formation of ice in the No Frost system?
With frequent use and poor sealing of the seals, ice formation may accelerate due to active air exchange. It is recommended to (check) the drainage hole and, if necessary, defrost the refrigerator once a year.
